Description

Technical Field

[0001] This utility model relates to the field of feeder technology, and in particular to an integrated feeder that can push forward and retract backward. Background Technology

[0002] In the automated labeling, packaging, and printing industries, accurate label feeding is a key factor in ensuring efficient production. Traditional feeding methods (such as unidirectional feeding or manual labeling) suffer from low efficiency, large positional deviations, and easy label sticking, making it difficult to meet the demands of high-speed and high-precision production. To address this, the label push-and-retract feeder has emerged. Through the coordinated actions of pushing and retracting, it achieves stable label peeling and continuous feeding. The pushing mechanism ensures that the label accurately reaches the peeling position for easy gripping by the label suction head, while the retracting mechanism adjusts the tension of the backing paper to prevent label misalignment or backing paper breakage. This technology is widely used in industries such as food, pharmaceuticals, and electronics, and is especially suitable for precision labeling scenarios such as self-adhesive labels and film labels. As automated equipment develops towards higher speeds and greater intelligence, optimizing the push-and-retract control logic and improving feeding stability have become important research directions in the industry.

[0003] The feeders on the market use a first-pick-then-stripping mode, which has high output accuracy and is very effective for materials that are difficult to strip or have shift or wrinkles after stripping. However, most existing retractable feeders use gear and rack drive for retracting the stripping platform when adjusting the stripping blade. It is not possible to switch or change to other drive methods on the frame, resulting in a relatively simple drive method for the stripping blade retracting platform, which has certain limitations. Utility Model Content

[0004] The main purpose of this utility model is to propose a forward-pushing and backward-retracting integrated feeder, which aims to solve the technical problem that most existing backward-retracting feeders use gear and rack drive for backward stripping when adjusting the stripping blade retraction platform, making it impossible to switch or replace other drive methods on the frame. This results in a relatively simple drive method for the stripping blade retraction platform, which has certain limitations.

[0005] To achieve the above objectives, the present invention proposes a forward-pushing and backward-retracting integrated feeder, comprising a frame, a feeding roller on the left side of the frame, a slide rail on the rear inner wall of the frame, a slider slidably connected to the slide rail, a moving plate on the slider, a peeling blade retraction platform on the moving plate, a non-stick plate on the frame, a winding roller on the inner wall of the frame, a protective cover on the frame, and a drive assembly on the inner bottom wall of the frame capable of driving the peeling blade retraction platform.

[0006] Optionally, the drive assembly is one of a lead screw assembly, a cylinder assembly, and a gear and rack assembly.

[0007] Optionally, the lead screw assembly includes a stepper motor, a lead screw, and a kit. The stepper motor is disposed on the inner wall of the frame, the lead screw is connected to the output end of the stepper motor, and the kit is sleeved on the lead screw, with its rear side fixedly connected to the front side of the moving plate.

[0008] Optionally, the kit is fixedly connected to the movable plate by bolts.

[0009] Optionally, the cylinder assembly includes a cylinder and a connecting block, the cylinder being disposed on the inner wall of the frame, and the connecting block being disposed at the output end of the cylinder.

[0010] Optionally, the connecting block is fixedly connected to the movable plate by bolts.

[0011] Optionally, the gear and rack assembly includes a second stepper motor, a rotating shaft, a gear, and a rack. The second stepper motor is disposed on the inner wall of the frame, the rotating shaft is connected to the output end of the second stepper motor, the gear is sleeved on the rotating shaft, and the rack is disposed on the movable plate and meshes with the gear.

[0012] Optionally, the rack and the movable plate are fixedly connected by bolts.

[0013] The technical solution of this utility model has the following beneficial effects:

[0014] When it is necessary to drive the peeling blade retraction platform to retract so that the suction cup can pick up the label on the material strip, start stepper motor one, the lead screw drives the moving plate on the kit to move backward. At the same time, the peeling blade retraction platform moves backward through the limit of the slider and slide rail, so that the bottom strip of the label on the suction cup is wound backward and separated from the label.

[0015] When it is necessary to drive the peeling blade retraction platform to retract so that the suction cup can pick up the label on the material strip, the cylinder is activated and the connecting block drives the moving plate to move backward. At the same time, the peeling blade retraction platform moves backward through the limit of the slider and the slide rail, so that the bottom strip of the label on the suction cup is wound backward and separated from the label.

[0016] When it is necessary to drive the peeling blade retraction platform to retract so that the suction cup can pick up the label on the material strip, the second stepper motor is started. The shaft drives the gear to rotate, which causes the rack to move the moving plate backward. At the same time, the peeling blade retraction platform moves backward through the limit of the slider and the slide rail, causing the bottom strip of the label on the suction cup to be wound backward and separated from the label.

[0028] This utility model proposes an integrated feeder that can push forward and retract backward.

[0029] like Figures 1 to 5 As shown in one embodiment of this utility model, the push-back and retractable integrated feeder includes a frame 1. A feeding roller 2 is provided on the left side of the frame 1, which facilitates feeding the labeled strip. A slide rail 3 is provided on the rear side of the inner wall of the frame 1. A slider 4 is slidably connected to the slide rail 3. A moving plate 5 is provided on the slider 4. A peeling blade retraction platform 6 is provided on the moving plate 5. A non-stick plate 10 is provided on the frame 1. A winding roller 11 is provided on the inner wall of the frame 1, which facilitates the winding of the bottom strip. A protective cover 12 is provided on the frame 1. A drive assembly that can drive the peeling blade retraction platform 6 is provided on the inner bottom wall of the frame 1. The protective cover 12 facilitates the protection of the drive assembly and other components inside the frame 1.

[0030] Specifically, the drive assembly is one of the following: lead screw assembly 7, cylinder assembly 8, and gear and rack assembly 9.

[0031] Example 1

[0032] Specifically, the lead screw assembly 7 includes a stepper motor 71, a lead screw 72, and a kit 73. The stepper motor 71 is located on the inner wall of the frame 1. The lead screw 72 is connected to the output end of the stepper motor 71. The kit 73 is fitted onto the lead screw 72 and its rear side is fixedly connected to the front side of the movable plate 5.

[0033] Specifically, the kit 73 is fixedly connected to the movable plate 5 by bolts. When it is necessary to drive the peeling knife retraction platform 6 to retract so that the suction cup can pick up the label on the material strip, the stepper motor 71 is started and the lead screw 72 drives the movable plate 5 on the kit 73 to move backward. At the same time, the peeling knife retraction platform 6 moves backward through the limit of the slider 4 and the slide rail 3, so that the label bottom strip on the suction cup is wound backward and separated from the label.

[0034] It should be noted that the micron-level control is achieved through microstepping drive, which enables tiny step angles (e.g., 0.045° after microstepping of a 1.8° motor). Combined with a high-precision ball screw (lead error ±0.02mm), the feeder movement resolution reaches the micron level. There is no cumulative error: under open-loop control, each step of the stepper motor strictly corresponds to the displacement of the ball screw. Even without a feedback system, the repeatability of positioning accuracy (e.g., ±0.05mm) can be guaranteed, making it suitable for precision feeding.

[0035] Example 2

[0036] Specifically, the cylinder assembly 8 includes a cylinder 81 and a connecting block 82. The cylinder 81 is located on the inner wall of the frame 1, and the connecting block 82 is located at the output end of the cylinder 81.

[0037] Specifically, the connecting block 82 is fixedly connected to the moving plate 5 by bolts. When it is necessary to drive the peeling knife retraction platform 6 to retract so that the suction cup can pick up the label on the material strip, the cylinder 81 is activated. The connecting block 82 drives the moving plate 5 to move backward. At the same time, the peeling knife retraction platform 6 moves backward through the limit of the slider 4 and the slide rail 3, so that the label bottom strip on the suction cup is wound backward and separated from the label. The cylinder 81 can achieve millisecond-level action response by means of pneumatic transmission characteristics, and the retraction speed is up to 0.5m / s.

[0038] Example 3

[0039] Specifically, the gear and rack assembly 9 includes a second stepper motor 91, a rotating shaft 92, a gear 93, and a rack 94. The second stepper motor 91 is located on the inner wall of the frame 1. The rotating shaft 92 is connected to the output end of the second stepper motor 91. The gear 93 is sleeved on the rotating shaft 92. The rack 94 is located on the movable plate 5 and meshes with the gear 93.

[0040] Specifically, the rack 94 and the moving plate 5 are fixedly connected by bolts. When it is necessary to drive the peeling knife retraction platform 6 to retract so that the suction cup can pick up the label on the material strip, the stepper motor 91 is started, the shaft 92 drives the gear 93 to rotate, so that the rack 94 drives the moving plate 5 to move backward. At the same time, the peeling knife retraction platform 6 moves backward through the limit of the slider 4 and the slide rail 3, so that the bottom strip of the label on the suction cup is rolled up and moved backward, separating from the label. High rigidity transmission: the meshing transmission of gear 93 and rack 94 has extremely high mechanical rigidity and load-bearing capacity, and can stably withstand a retraction force of more than 200N, ensuring reliable peeling of thick labels such as metal foil labels. Long stroke accuracy guarantee: the rack linear guide structure can still maintain a positioning accuracy of ±0.05mm within a one-meter stroke, far exceeding the cylinder drive solution, and is particularly suitable for large-format label feeding.

[0041] In summary, the lead screw assembly 7, cylinder assembly 8, and gear and rack assembly 9 can all be disassembled and replaced by bolts and moving plate 5. This allows customers to select the drive mode of the stripper retraction platform 6 according to the performance requirements of their products, thus making it adaptable to different specifications of strip materials and enabling it to achieve efficient feeding, avoiding the limitations of integrated push-back and retraction feeders.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
